Endesa’s networks subsidiary e-distribución connected almost 81,800 self-consumption facilities in 2022, compared with 25,000 during 2021.
These new connections brought the total to 115,192 active installations across the company’s distribution network, which covers Andalusia, Extremadura, Catalonia and Aragon and the Balearic and Canary Islands.
Together, these installations had a joint installed power of 2.48GW, amounting to almost half of the power of the total active self-consumption facilities in Spain in 2022 and equivalent to almost 60% of the energy produced in the power plants, thus avoiding about 2.1Mt of CO2 during the year.
Endesa attributes this increase to a growing momentum of self-consumption in Spain, and accelerated by the high energy prices resulting from the conflict in Ukraine.
And the number has continued to grow during 2023 with almost 150,000 active installations with a combined capacity of 2.68GW by the end of February.
Endesa estimates that almost 99% of the self-consumption customers have surpluses that they feed into the grid, with provisional calculations estimating they delivered 248,000MWh in 2022, equivalent to the consumption of approximately 71,000 homes.
Just 1% are believed not to have a surplus.
The majority also are individual and just 160 are collective or community facilities.
Endesa reports that Andalusia and Catalonia concentrate the majority of self-consumption facilities, while the largest growth in 2022 was recorded in Aragon and the Canary Islands.
The Balearic Islands also have among the highest rates, at a level of one facility per every 190 inhabitants.
Endesa cites Spanish Solar Photovoltaic Association data of a total of 5.29GW of installed self-consumption capacity at the end of 2022.
The government is targetting between 9GW to 14GW by 2030 – a figure which is likely to be met earlier if the current trend is maintained.
